GeoData 250k Topographic Data - ARC

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\nContains a medium scale vector representation of the topography of Australia. The data include the following themes: Hydrography - drainage networks including watercourses, lakes, wetlands, bores and offshore features; Infrastructure - constructed features to support road, rail and air transportation as well as built-up areas, localities and homesteads. Utilities, pipelines, fences and powerlines are also included; Relief - features depicting the terrain of the earth including 50 metre contours, spot heights, sand dunes, craters and cliffs; Vegetation - depicting forested areas, orchards, mangroves, pine plantations and rainforests; and Reserved Areas - areas reserved for special purposes including nature conservation reserves, aboriginal reserves, prohibited areas and water supply reserves. Additional Metadata an be obtained from the following site: http://www.ga.gov.au/meta/ANZCW0703005458.html Showing Topographic Data captured from 1:250,000 scale maps, and includes: Aircraft Facilities, Buildings, Built up areas, Contours, Drainage, Morphology, Utilities, Placenames, Roads and Railways.\n\n## **Purpose** \n\nUsed as a guide to the display of Topographic features.\n\n## **Dataset History** \n\nGEODATA TOPO 250K Series 3 is primarily sourced from GEODATA TOPO 250K Series 2 and 1:250 000 scale map reproduction material (from the National Topographic Map Series and Defence Joint Operation Graphics). A key revision source for the data is satellite imagery taken from the SPOT Panchromatic and LANDSAT Thematic Mapper Sensors. Revision material has also been gathered from a variety of authoritative sources. More information about the sources for this data can be found in Geoscience Australia's Topographic Data and Map Specifications.\n\n## **Dataset Citation** \n\nSA Department of Environment, Water and Natural Resources (2015) GeoData 250k Topographic Data - ARC.
